Abstract
The utility model relates to a motor with functions of ventilation and heat dissipation. The motor comprises a motor base, and a motor shaft, a rotor and a stator are installed in the motor base. The motor is characterized in that: more than one ventilating hole which stretches through the rotor form one end to the other end along the axis direction of the rotor are arranged on the rotor. In the motor with the functions of the ventilation and heat dispersion, effective ventilating and heat-dissipating effects on the motor can be realized, so that the reduction of the heat in the motor is benefited, and the loss of the stator and the rotor is avoided.
Description
Technical field
The utility model relates to a kind of motor with ventilation and heat function.
Background technology
At present, on motor, existing heat dissipation technology mainly is to dispel the heat by the radiating ribs on the support, can't be dispersed into the motor outside to the motor internal heat to greatest extent, so make heat accumulation that motor internal produces in motor, can make that not only power of motor is on the low side, also cause the big phenomenon of iron, copper and aluminium consumption of stator and rotor to take place easily.
Summary of the invention
In order to solve existing in prior technology the problems referred to above, the utility model provides a kind of motor with ventilation and heat function, it can play effective ventilation and heat effect to motor, thereby helps reducing the motor internal heat, avoids the loss of stator and rotor.
The purpose of this utility model is achieved through the following technical solutions: a kind of motor with ventilation and heat function, it comprises support, be provided with motor shaft, rotor and stator in the support, it is characterized in that: described rotor is provided with the ventilating hole channel that is extended the penetrating extremely axial other end more than by an axial end of rotor.
In addition, the utility model technique scheme has also been done following improvement:
For the ease of flowing of air, the duct trend of described ventilating hole channel has suitable deflection with the axial direction of rotor.
Owing to can make the air of rotor rear and front end have certain draught head at the effect lower rotor part high speed rotating of electromagnetic force, therefore can be in the ventilating hole channel of rotor, air gap and the air between the portion of rotor rear and front end between stator and the rotor form circulation.Under the effect of flowing gas, constantly with the air gap between stator and the rotor and the heat transferred in the rotor on the front end housing and rear end cap of support, thereby reduce the temperature rise of motor, raising motor operating efficiency.
The rear and front end of support is respectively equipped with front end housing and rear end cap, is distributed with radiating ribs on the surfaces externally and internally of described front end housing and/or rear end cap.The radiating ribs of described front end housing and/or rear end cap outer surface can be orthogonal thereto arranged evenly, and the radiating ribs of described front end housing and/or rear end cap inner surface can stagger and radial ringwise arrangement mutually.Adopt this structure, its area of dissipation increases and radiating rate improves, and can effectively absorb the heat of motor, so good heat dissipation effect, the generator long service life.
Described rear end at motor shaft also is provided with fan and covers at the fan housing at fan rear.
